Hi, Had M100 v1.0.1 and Boris Red 188.8.131.527. Just tried upgrading to M100 v.1.1.3 but it didn't solve the problem, =(.
Problem is that a composition clip in the video track only ever renders black. The preview works fine, problems only occur on render. The clip is a Boris Red project, so basically some 3D planes with some text.
I tried the render range work around (via "Render..."), and it didn't make any difference, =(.
